The results of the monitoring show that at least four of eight bat species that live in Illinois are also found in and around Chicago. Although the researchers have identified big brown bats, eastern red bats, silver-haired bats, and hoary bats, from their calls, they are still not sure where exactly the bats live or how many there are.

Now they have asked for the public to report bat sightings in hopes of getting a clearer picture of the distribution of the species prior to the appearance of WNS.
